1. Sensitivity analysis of the AquaCrop model for wheat crop in Campos Gerais region, Paraná
ABSTRACT The use of crop modeling can be useful to understand the interactions between the soil-plant-atmosphere system. The objective of this study was to evaluate sensitivity analysis of the AquaCrop model parameters for wheat crop in the Campos Gerais Region. The varietie tested was TBIO Sinuelo in Castro, Ponta Grossa and Itaberá cities. The analyzed pa

5. PHYSICAL-HYDRAULIC PROPERTIES OF AN ULTISOL UNDER NO-TILLAGE AND CROP-LIVESTOCK INTEGRATION IN THE CERRADO
RESUMO Os solos leves possuem maior suscetibilidade ao processo de degradação e necessitam ser explorados de forma conservacionista, evitando assim sua rápida degradação. Objetivou-se com o estudo avaliar as propriedades físico-hídricas de um Argissolo sob plantio direto e integração lavoura-pecuária no Cerrado da região leste do estado do Maranh�

6. PHYSICAL-HYDRAULIC ATTRIBUTES AS INDICATORS OF FUNCTIONALITY OF SOIL PORES UNDER DIFFERENT COMPACTION LEVELS
RESUMO A compactação modifica o arranjo estrutural e as funções essenciais dos poros do solo. O trabalho teve como objetivo avaliar o impacto de diferentes graus de compactação em um Argissolo Amarelo sobre os atributos físicos-hídricos indicadores da funcionalidade dos poros. Foram utilizados cilindros de solo 0.05 x 0.05 m em 4 graus de compactaç�

7. Soil stabilization with lime for erosion control in solar plants
Abstract The installation of solar parks requires extensive areas and results in soil erosion in many cases. One suitable solution is applying lime to improve soil characteristics, such as mechanical strength, stability, workability, durability, and internal and surface erosion resistance. This soil treatment is of particular importance when dealing with hyd

8. Evaluation of the combined addition of aluminum lactate and calcium carbonate to alumina-based castables
Abstract Calcium aluminate cement (CAC) can induce the development of high green mechanical strength to refractory castables in a short period of time (24 h). However, the production of this hydraulic binder is energy-intensive and releases a large content of carbon dioxide (CO2), which adds to global warming. Thus, aiming to develop an alternative binding s

9. BIOGAS YIELD AND PRODUCTIVENESS OF SWINE MANURE FOR DIFFERENT REACTOR CONFIGURATIONS
ABSTRACT The progression of the organic loading rate (OLR) up to a certain limit increases biogas production. The limit and operation range vary according to the configuration of the reactor and are associated with other variables that generate different results with respect to biogas yield (BY) and biogas productiveness (BP). The aim of this study was to in

12. Large strain consolidation analyses of fine tailings disposal in mining pits
Abstract Herein, three-dimensional analyses of large strain consolidation applied to tail ings disposal in mining pits is studied. The main goal is to estimate filling time and, ac cordingly, the capacity of the pit. Other useful results, such as dry density profiles and water pore pressure generation are also obtained. Two different slimes from the iron or
